### What?
Switch the default for `--turbo` to the new `--experimental-turbo`, remove the old code in next.js
### Why?
The new approach will be used in future
Closes WEB-1506
### 🧐 What's in there?
As discussed with @huozhi, it's restoring code from #52393 which I forgot to restore in #54891.
It is unlikely to make a difference, but we'll set globalWindow based on the desired test environment. This will not make any difference for most people.
### 🧪 How to test?
Once you've rebuilt your local version of Next, `pnpm testheadless jest/rsc`

### What
Pairing PR to https://github.com/vercel/turbo/pull/5714, which I believe last piece to reenable correct datadog test reports for daily next.js integration + turbopack.
1. Creates a unique suite name to avoid collision / merging across different env / grouped test run
2. revert suitename template (which is for _suites_, not _suite_ for top level) as 1 resolves uniqueness
### What?
this forces all tests to use turbopack independent of the way they invoke next dev
### Why?
some tests were not running turbopack
fixes WEB-1187
### What?
WEB-1150.
This PR is an attempt to upload next.js's test results into datadog test trace to track its status.
Originally it tried to use automatic trace injection (dd-trace/ci/init). However, due to some of custom environments / setup we use it was not compatible out of the box. Instead, this PR injects a new test reportert to generate junit report, then upload it at once at the end of the testing pipeline.
The reporter is configured to run when necessary variables set, local run should not be affected.
One thing to note is this report will not count retry results, as it'll create duplicated test entry with multiple results since we runts jest per individual test. This'll allow to detect flaky test easier, but also it means we'll get bit of skewed test results compare to the real world as first failure will be accounted as test fail immediately.
Refactor the logic of picking the font file to use for the font fallback
generation. Add additional tests that checks that the correct font file
is picked. Also adds more comments explaining the logic and assumptions
behind the functions.

This PR adds a new `experimental.enableUndici` option to let the
developer switch from `next-fetch` to `undici` as the underlying
polyfill for `fetch` in Node.js.
In the current implementation, Next.js makes sure that `fetch` is always
available by using `node-fetch`. However, we do not polyfill in Node.js
18+, since those versions come with their own `fetch` implementation
already, built-in.
Node.js 18+ uses `undici` under the hood, so letting the developer use
`undici` earlier could make the migration easier later on.
Eventually, we hope to be able to stop polyfilling `fetch` in an
upcoming major version of Next.js, shipping less code.

* Add tsx extension to jest config
* bump
This updates our `jest` configuration to no longer use `babel-jest` and instead uses `@swc/jest` which is much faster. This also updates to the latest version of `jest`, fixes our `tsconfig.json` used for tests (previously types in `node_modules` weren't resolved correctly), and ensures `next/dist` isn't un-necessarily transpiled in `jest`.

This PR upgrades `jest-worker` and `jest-cli` to the latest pre-release version, also removed `jest-circus` which is included in Jest by default. `jest-worker@next` includes a fix for memory leak that we need (https://github.com/facebook/jest/pull/11187).
Fixes#22925. This will also improve the OOM issue for `next dev` #15855.
Update tests to setup webdriver stuff in `jest-environment` and re-use one browser session instead of spawning one for each webdriver call to prevent creating too many BrowserStack sessions.
- [x] Move jest config from npm scripts to `jest.config.js`
- [x] Remove obsolete cross-env package (we don't need it anymore 🎉)
- [x] Fix bug where tests are not waiting for webdriver to be ready.
